Hello Zahid, Here is the code and it works. I am not sure which programming language you are using but you could convert it. Thanks, James ... View more

Hello Keith, Maybe you could use arcGIS to classify an image for a landcover analysis. Once the landcover analysis is complete, then use the ipad to ground truth your landcover analysis. By using the ipad, it could be either point, line, and/or polygon. You may be able to download a GPS application to use and export the files. Hope this helps! James ... View more

Hello Stacy, Click on the 'Set Up Data Driven Pages' icon and click on the second tab called Extent. Click the Data Driven Scale radio button. From the drop down menu, select the attribute field with the scale. This work for me using my data. Thanks, James ... View more

Hello Torika, Dan is correct. You can calculate it by using a Digital Elevation Model (DEM) or a National Elevation Dataset (NED). Simply extract values using a point shapefile and the elevation model raster. This will give you the Z values. Thanks James ... View more

Hello Kira, It is possible to create custom shapes. It does, however, require python code to perform it. I can pass some code along to you. It basically works, in a manner, where the user drops a point and then draws a polygon. I used it to create many polygons based on zoning. The polygons were basic shapes based on length and height. If you had several custom shapes, then code would have to account for the dimensions.Also, you would have to start an edit session to orient the shapefiles. Let me know if you want the code James ...

Hello Adam, Not sure if you can export shapefiles.shp from Business Analyst Online. It may depend on product's package subscription. If there are not many attributes to tag, then you may be able to georeference a screen shot and create shapefiles. Time consuming yes but affordable too. James ... View more
